Chamilo is an e-learning and collaboration platform. Chamilo is currently used by more than 7,000,000 students around the world. Governments, private companies, public and private universities, and NGOs use the Chamilo software suite to manage activities from simple live training to full distant learning, certification, and staff selection.
Pytilities offers AOP and monkey-patching features for Python 3. Pytilities also offers other features such as help in delegating calls to an inner object, function overloading, some special descriptors, geometry classes, event dispatching classes, and more. The AOP features allow you to make reusable Aspect classes, (un)apply multiple aspects to an instance or class, add new attributes to an instance, and apply advice to all attribute access of an instance or class.
Zebra_MPTT is a PHP class that provides an implementation of the modified preorder tree traversal algorithm. It provides methods for adding nodes anywhere in the tree, deleting nodes, moving and copying nodes around the tree, and for retrieving information about the nodes. It uses table locks to ensure that database integrity is always preserved and that concurrent MySQL sessions don’t compromise data integrity. A caching mechanism ensures that regardless of the type or the number of retrieval operations, the database is read only once per script execution.
Jipes is a Java library that allows you to efficiently compute audio features. Possible uses for these features are general music information retrieval (MIR) applications or, more specifically, personal music software. Unlike many other digital signal processing (DSP) libraries or frameworks, Jipes is not meant for real time processing of a single audio stream that is manipulated and eventually played back. Instead, it focuses on efficiently executing mutiple processing pipelines that transform a signal into a feature or feature set. Since Jipes focuses on features instead of the raw, untyped signal streams, it supports rich types to be used, where other frameworks only offer arrays of raw data. Also, by using Java generics, many core interfaces and classes can be typed to whatever class you see fit for the purpose. However, Jipes also comes with useful pre-defined types and support for raw arrays.
pyexpander is a macro processor based on Python. Instead of simple text replacement, it offers evaluation of arbitrary Python expressions and execution of Python code. It features simple syntax definition: all expander commands start with a dollar sign ("$") followed by word characters, parameters, Python code enclosed in brackets, or a combination of these. The full power of the Python programming language can be used, including all operators, functions and modules. Any Python expression can be used to insert text. It also provides a Python library that you can use to develop other macro tools based on pyexpander.
